LibWeb: Make Paintable::containing_block() return a PaintableBox*
Every single client of this function was immediately calling paintable() on the result anyway, so there was no need to return a layout node! This automatically leverages the cached containing block pointer we already have in Paintable, which melts away a bunch of unnecessary traversal in hit testing and painting. :^)
